Hello,
1- Is there a way to report when clients connect and disconnect?
2- Is it possible to notify the connection of a specific client to
the server through email?
On the server, you can use the client-connect/disconnect config. Just
fire whatever script you want from there to do whatever notification
you want. Various environment vars get populated (e.g. X509_0_CN)
that you can save as needed and tune your notifications to match what
you need.
client-connect "/usr/local/etc/openvpn/connect.sh"
client-disconnect "/usr/local/etc/openvpn/disconnect.sh"
Hi,
Thank you.
I mean, does OpenVPN itself have the ability to keep the IP address of
the client and the time it is connected to the server somewhere for
reporting?
I am not sure what you are after. OpenVPN keeps track of all that
information and more (IP address of the client, time, username etc) and
exports them in environment variables which you can make use of at
client connect / disconnect time. You can then do with them as you
require to meet your reporting requirements.
e.g. here is what I log
Feb 12 01:01:30 gate2a UP[85616]: joe-mac ME 10.21.1.1 REMOTE 10.21.1.38
FROM 129.222.114.2
Feb 12 01:02:38 gate2a DOWN[85759]: joe-mac ME 10.21.1.1 REMOTE
10.21.1.38 FROM 129.222.114.2
the connect.sh script that logs that in one of my server's openvpn.conf
file.
/usr/bin/logger -p local2.notice -t UP $common_name ME $ifconfig_local
REMOTE $ifconfig_pool_remote_ip FROM $untrusted_ip
